' SPECIFICATION forming part of Letters Patent No. 255,666, dated March28, 1882.

Application filed January 14, 1882. (No model.) I

' To all 'LthOlll/il may concern:

had to the accompanying drawings, and to theletters of reference markedthereon, which form part of this specification, and in which- Figure 1is a side elevation, showing the valve in one position; and Fig. 2, acentral ver tical section, showing it in the other.

This invention relates to steam and water valves which are provided withconical gates applied on screw-stems and fitted to seats in the body ofthe valve.

The nature of my invention consists in an angle valve body provided withseats for the gate arranged at right angles to each other, incombination with a removable cap applied to one of the taps of thevalve-body, as will be hereinafter explained.

I am aware that it is not uewto construct a globe-valve with a diaphragmhavingdouble seats for the gate eitherof which can be used at pleasure,and therefore I 'donot claim broadly a double-seat valve.

t The following is a description of my improved valve.

In the annexed drawings, A designates the body of the valve, which isconstructed with four screw-tapped branches, a b c d, and which may beof any suitable capacity. Atthe inner terminus of thepassage or brancha, I form a valve-seat, c, and at the inner terminus of the passage orbranch b, I form another seat, f, corresponding in size to the seat c.It will be seen that the two seats are at right angles to each other,and that the two branches a b form a direct water-way through the valvebox or body A. g

B designates the conical gate, which is adapted to fit on either one ofthe seats, and which is suitably applied on a screw-stem, 0, so that itcan swivel thereon. The screw-stem (J is tapped though a screw-cap andstufling-box, D,

which may be screwed either into the branch d, as shown in Fig. 1, orinto branch 0,-as shown in Fig. 2. When the gateB is arranged to act onthe seat f the branch 0 of the body said cap E. It' will be seen that- Ihave a reversible or interchangeable valve-box, either? seat 0f.whichcan be used at pleasure; also,

that I have an unobstructed flow of water or steam from one branch, I),to the other, a. I

dispense with the internal double-seated'diavided with internalvalve-seats, at right angles to each other, in combination with cap Eand stutfing-box D, adapted to be interchangeably screwed upon the othertwo branches of the valve-shell, and the valve B, as and for the purposeset forth.

In. testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
